This invention relates to attachments i01- oil cans designed for thepurpose of aldlng the forcing of oil into'oil cups, oil holes andlubricating orifices generally.

i 5 With the ordinary oil can the oil, asit is forced out by pressing onthe bottom of the p can, enters the lubricating orifice by gravity andcannot be forced down under pressure to the bearing surfaces owing tolack of pressure-tight contact between the can spout and the lubricatingorifice.

Screw nipples have beenemployed tornake fluid tight connection betweenthe lubrlcant container and the lubricating orifices sothat thelubricant may be injected into such ori: fices under pressure. Thismethod, however, limits the use of such lubricant containers tolubricating orifices which have been specially constructed to receivesuch screw nipples.

The object of the present invention is to provide means for soconnecting the spout of an ordinary oil can to substantially anylubricating orificethat oil may be forced lnto the latter underpressure.

i Other and furtherimportant objects of this invention will be apparentfrom the disclosures in the accompanying drawings and the followingspecification. V V

The invention (in apreferred form) is illustrated on the drawings andhereinafter more fully described. On the drawings:

The end of the rubber sleeve, being resilient, makes tight contact withlubricating;

orifices of almost any shape or construction. As shown in Figure 5,'theattachment may have end contact with the slightly cupped end of an oilhole 8' in a bearing 9 orthe like.

5 In Figure 6, a lubricating nipple 10 is So I Preferably, ainetal"retaining sleevelijis arranged around the rubber sleeve to prevent ilatterp Conveniently an annular shoulder is y shown, which can be forcedinto the end of the attachment.

In Figure 7, a grease cup 11 is illustrated with which the attachmentmakes peripheral contact.

In Figure 8 is shown an oil-cup 12 provided with a ball check-valve 13normally held closed by a spring 1%. The end of the attachment contactswith the ball 13 and presses it away from its seat and at thesame timeseals the orifice so that the oil in the can may be discharged underpressure into the cup 12.

Whatever the method of engagcn'ient or contact may be when the bottom ofthe oil can is depressed, oil is forced into the lubricating orifice.The can and its attachment is then raisedor tilted to break the contactand the pressure on the bottom of the can released. The bottom springingback produces suction in the can, and as contact has been broken, airdrawn into the can. Contact is then re stored between the attachment andthe lubricating orifice. hen the bottom of the can is again depressed, afurther quantity of oil is forced. into the lubricating orifice and theoperation is repeated as often as desired.

A modified term of construction is shown in Figure 9. In this case, theend of the oil can spout is formed with a cup 15 into which one end ofthe attachment 16 may be slipped.

I am aware that many changes may be made, and numerous details ofconstruction may be varied through a wide range without departing fromthe principles of this invcntion, and I therefore do not purposelimiting the patent granted hereon, otherwise than necessitated by theprior art.

I claim as my invention 1. An oil can attachment comprising a resilientsleeve having a hemispherical outer end, a metallic band therearmmd toprevent spreading of said attachment, said sleeve being adapted toengage the spout of an oil can with the hemispherical end projectingbeyond the tip of said spout.

2. An oil can comprising a spout, a resilient sleeve in engagement withsaid spout A 1d a shoulder on said spout below the end 0. the

same to ensure that the end of said sieeve projects beyond the tip ofsaid spout.

3. An oil can attachment comprising a. resilient sleeve adapted toengage the spout of an oil can with one end projecting beyond the tip ofsaid spout, said end being of hemispherical form.

In testimony whereof I have hereunto sub scribed my name.
